ECO-WORTHY 12V 20A DC to DC Charger with Solar Charge Controller

The DC-DC battery charger is installed between the starter battery and the leisure battery, or between the solar panel and the leisure battery. It allows you to charge your leisure battery by pulling power from your vehicle's alternator or solar panel.

The DC-DC charger adopts maximum power point tracking technology (MPPT) to ensure that it converts most of the energy by locking to the maximum power point. This MPPT charging mechanism works by quickly tracking the maximum power point of the photovoltaic array, with a tracking efficiency of up to 99%, significantly improving the energy-harvest from your solar panels.

The charger supports input from both the alternator (12.4-16V) and solar panels (16-25V) at the same time. It will automatically choose the alternator input when both solar and alternator inputs meet the charging condition.

The charger provides the following specifications: Input: DC Battery 12.4-16V, Solar Input 16-25V Output/Charging Voltage: 14.4-15.5V Output Current: DC Output 20A, Solar Output 20A Minimum Start Voltage: 2V for the battery being charged Soft Start: Yes Soft Charge Current: 20A Bulk Charge Voltage: 14.7V (AGM/Gel), 14.4V (Lead Acid/Li), 15.4V (Ca) Absorption: Constant Voltage with Automatic Amperage Control Equalization: Automatic Float Charge Voltage: 13.5V (AGM/Gel/Lead Acid/Ca) Float Charge Current: 100mA Battery Range: 18 to 250Ah

The ECO-WORTHY DC-DC charger features a built-in solar charge controller, making it a 2-in-1 charger with both generator starting battery input and solar panel input. It is suitable for various battery types, including AGM/GEL, lead acid, lithium, and calcium batteries.

The charger's intelligent MPPT charging system includes a charging memory feature, which records the user's charging habits to optimize the charging process.

For enhanced safety, the charger has one-way charging to prevent reverse charging and power consumption from the house battery. It also includes engine start battery low-voltage protection, as well as overcharging and short-circuit protection to extend the battery lifespan.

The charger is easy to use, with clearly labeled wiring for solar panels, alternator, and battery. Indicator lights are provided for normal charging connections, ensuring easy identification of any abnormal connections.
